The share price of the most-valuable company in South Australia has broken through a key milestone.

Oil and gas giant Santos – South Australia’s top company for 2026 – cracked a share price milestone last week, breaking through the long-awaited $9 per share mark.
It achieved the milestone last Tuesday morning and closed out the week up almost four per cent to land an almost $30 billion market capitalisation.
The rally may continue ahead of the company releasing its third-quarter results later this month.
And analysts remain bullish on Santos, with Morgan Stanley tipping shares could rise to $9.31 – a 20c per share rise from Friday’s closing price of $9.11.
Santos was once again named SA’s top company for the year in InDaily’s South Australian Business Index.
